discuz定义的函数showmessage()可以将弹窗以AJAX的方式弹出,首先要将模板文件中的表单按照格式编写按照格式编写.

模板文件

<!--{elseif $_G['gp_op'] == 'transfer'}-->

			<!--{if $_G[setting][transferstatus] && $_G['group']['allowtransfer']}-->
			<form id="transferform" name="transferform" method="post" autocomplete="off" action="home.PHP?mod=spacecp&ac=credit&op=transfer" onsubmit="ajaxpost(this.id,'return_transfercredit');">
				<input type="hidden" name="formhash" value="{FORMHASH}" />
				<input type="hidden" name="transfersubmit" value="true" />
				<input type="hidden" name="handlekey" value="transfercredit" />
				<table cellspacing="0" cellpadding="0" class="tfm mtn">
					<tr>
						<th>{lang memcp_credits_transfer}</th>
						<td class="pns">
							<input type="text" name="transferamount" id="transferamount" class="px" size="5" style="width: auto;" value="0" />
							{$_G[setting][extcredits][$_G[setting][creditstransextra][9]][title]}
							{lang credits_give}
							<input type="text" name="to" id="to" class="px" size="15" style="width: auto;" />
						</td>
						<td width="300" class="d">
							{lang memcp_credits_transfer_min_balance} $_G[setting][transfermincredits] {$_G[setting][extcredits][$_G[setting][creditstransextra][9]][unit]}<br />

						<td><input type="password" name="password" class="px" value="" /></td>
					</tr>
					<tr>

					</tr>
					<tr>
						<th></th>
						<td colspan="2">

							<span style="display: none" id="return_transfercredit"></span>
						</td>
					</tr>
				</table>
			</form>
			<!--{/if}-->

<form id="transferform" name="transferform" method="post" autocomplete="off" action="home.PHP?mod=spacecp&ac=credit&op=transfer" onsubmit="ajaxpost(this.id,'return_transfercredit');">

看以上HTML的第5,6,7行,表单中必须的3个表单项:(重要)

<input type="hidden" name="formhash" value="{FORMHASH}" /><!--discuz所有表单都有此项,机制类似于验证码,保证表单来路安全-->  
<input type="hidden" name="transfersubmit" value="true" /><!--为保证各个浏览器兼容性,单独添加此项,以便在后台以if(submitcheck(transfersubmit))作判断,直接给button添加name或直接给form增加name,各版本浏览器不一定发送-->  
<input type="hidden" name="handlekey" value="transfercredit" /><!--AJAX必须添加此项,好像是一个标识符--> 

<span style="display: none" id="return_transfercredit"></span>

现在看一下以上3处命名规律:

onsubmit=ajaxpost(this.id,'return_transfercredit');

<input type='hidden' name='handlekey' value='transfercredit' />

<span style='display:none' id='return_transfercredit'></span>

这三个值必须保证固定格式return_xxx,xxx,return_xxx

程序文件如下:

elseif ($_G['gp_op'] == 'transfer') {

	if(!($_G['setting']['transferstatus'] && $_G['group']['allowtransfer'])) {
		showmessage('action_closed',NULL);
	}

	if(submitcheck('transfersubmit')) {
		if($_G['gp_to'] == $_G['username']) {
			showmessage('memcp_credits_transfer_msg_self_incorrect','',array(),array('showdialog' => 1,'showmsg' => true,'closetime' => true));
		}
		$amount = intval($_G['gp_transferamount']);
		if($amount <= 0) {
			showmessage('credits_transaction_amount_invalid','closetime' => true));
		} elseif(getuserprofile('extcredits'.$_G['setting']['creditstransextra'][9]) - $amount < ($minbalance = $_G['setting']['transfermincredits'])) {
			showmessage('credits_transfer_balance_insufficient',array('title' => $_G['setting']['extcredits'][$_G['setting']['creditstransextra'][9]]['title'],'minbalance' => $minbalance),'closetime' => true));
		} elseif(!($netamount = floor($amount * (1 - $_G['setting']['creditstax'])))) {
			showmessage('credits_net_amount_iszero','closetime' => true));
		}
		$to = DB::fetch_first("SELECT username,uid FROM ".DB::table('common_member')." WHERE username='$_G[gp_to]'");
		if(!$to) {
			showmessage('memcp_credits_transfer_msg_user_incorrect','closetime' => true));
		}

		loaducenter();
		$ucresult = uc_user_login($_G['username'],$_G['gp_password']);
		list($tmp['uid']) = daddslashes($ucresult);

		if($tmp['uid'] <= 0) {
			showmessage('credits_password_invalid');
		}

		updatemembercount($_G['uid'],array($_G['setting']['creditstransextra'][9] => -$amount),1,'TFR',$to['uid']);
		updatemembercount($to['uid'],array($_G['setting']['creditstransextra'][9] => $netamount),'RCV',$_G['uid']);

		if(!empty($_G['gp_transfermessage'])) {
			$transfermessage = dstripslashes($_G['gp_transfermessage']);
			notification_add($to['uid'],'credit','transfer',array('credit' => $_G['setting']['extcredits'][$_G['setting']['creditstransextra'][9]]['title'].' '.$netamount.' '.$_G['setting']['extcredits'][$_G['setting']['creditstransextra'][9]]['unit'],'transfermessage' => $transfermessage));
		}
		showmessage('credits_transfer_succeed','home.PHP?mod=spacecp&ac=credit&op=transfer','locationtime' => true));
	}

}

showmessage()会返回ajax弹窗需要用到的数据,客户端会将此数据保存到<span id="retrun_xxx" style="display:none"></span>以供弹窗使用

效果如下:

上面我们说的都是ajaxpost()方法,当我们点击某个链接删除时就要使用ajaxget()

如下图:

当点击"删除"时以ajaxget()方法操作,模板如下,注意href里必须添加handlekey=xxx:

<td><a onclick="delJob(this);return false;" href="home.PHP?mod=spacecp&ac=job_company&op=employ&do=del&handlekey=deljob&jid={$val['id']}">删除</a></td>

<span id="return_deljob" style="display:none"></span>

<script type="text/javascript">
    function delJob(item){
        if(window.confirm("您真的要删除这条信息么?")){
            var url = item.getAttribute("href");
            ajaxget(url,"return_deljob");
        }  
    }
</script>

if(empty($arr[person])){
           showmessage('人数不能为空','closetime' => true)); 
        }

if($res){
             showmessage('更新成功','home.PHP?mod=spacecp&ac=job_company&op='.$operation,'locationtime' => true));
        }

请注意showmessage()以下面这种方式使用只会弹出窗口,此时跳转url为空,'closetime'=>true;并且自动关闭:

showmessage('The message!','closetime' => true));
